I have a dell N7010 that I usually dont power off or close the lid, Someone in my family did so and all I get afterwards is 2MB wireless signal compared to 54MB usually. This has happened twice in the past 7 months. And alwasy after hibernation or sleep. I uninstall and reinstall drivers with no success. Built in network (wired) works just fine at 54MB.
I just reimaged my hard drive to fix this problem and it was working fine until overnight.
I had not set the power settings and it went to hibernation or sleep. I had to hit power button to resume windows. HELP
